3 phase to single phase

Seems like you found a major jackpot. Power conversion an option?

-- Ciao, gth.

I thought about it, I found some converters on craigslist average price is $225 to $250. But if it was not TO expensive, I was thinking of buying more than I need (as if there ever was such a thing as to many tools,lol).
Convert them all to 220 and then resale them. Of couse LJ’s would get a BIG discount, rest would go on craigslist. But I have to let him know by tomorrow what I will take, so I am trying to see if it is worth the investment or not.

You can either use a rotary phase converter that looks like a motor to make 3 phase from single phase power or use a variable speed drive to feed the motor. I’m not sure off the top of my head how much to over size the drive when feeding it with single phase, at least 1/3 to 1/2. It’s not the most efficient thing in the world, but it works. Probably cheaper than replacing the motors. Check Grainger, they have everything, just make sure the motor has the same frame and speed. Good luck :-)

Thanks Topamax,
Forgot all about Grainger, with out knowing frame and speed…just did a generic search…OMG !!!!!! 2hp woodworking motor for a contractor saw…$400.00. So much for my get rich quick idea :(

-- Don S.E. OK

I just googled and Grizzly showed up with 2 hp for about $220 and 5 hp for about $320. Not as bad as I thought they’d be :-))

No, thats not bad at all…220 I can handle. I am SERIOUSLY thinking of buying that 10 inch powermatic jointer. 350 for the jointer, lets say 250 for the motor with shipping, maybe another 100 for fixing little things….$700 for a ten inch powermatic would not be bad !!!

-- Don S.E. OK

I wouldn’t let a motor stand in my way of a good deal. Craiglist always has electric motors going up for sale. Grizzly is also good if you want a new motor.

I use a rotary phase converter in our machine shop and it will run a 7hp lathe and a small surface grinder simultaniously with no problems. If you go that route let me know and I will see what the rating is on it.
